A bad dream 歌词，想表达个啥？

Why do I have to fly
Over every town up and down the line?
I'll die in the clouds above
And you that I defend, I do not love

I wake up, it's a bad dream
No one on my side
I was fighting
But I just feel too tired
To be fighting
Guess I'm not the fighting kind

Where will I meet my fate?
Baby I'm a man, I was born to hate
And when will I meet my end?
In a better time you could be my friend

I wake up, it's a bad dream
No one on my side
I was fighting
But I just feel too tired
To be fighting
Guess I'm not the fighting kind
Wouldn't mind it
If you were by my side
But you're long gone
Yeah you're long gone now

Where do we go?
I don't even know
My strange old face
And I'm thinking about those days
And I'm thinking about those days

I wake up, it's a bad dream
No one on my side
I was fighting
But I just feel too tired
To be fighting
Guess I'm not the fighting kind
Wouldn't mind it
If you were by my side
But you're long gone
Yeah you're long gone now

真诚发问……【旋律太棒最近一直在脑内当BGM有点受不了了！
